给FreeSwitch集成了NV硬解。前几天突然报告说,登录A服务器,转发会议命令到B服务器后,一直没画面。跟踪了一下,是硬解一直失败。怎么办?先切换到软解,有时间再研究怎么回事。
- 正常来说,开始的时候,硬解返回数据都是空(因为是异步的)。所以,吾设定失败16次后切换。
- 切换代码如下:
static int init_decoder(h264_codec_context_t *context, final int hw, final int release)
{
avcodec_profile_t *profile = NULL;
profile = find_profile(get_profile_name(context->av_codec_id), SWITCH_FALSE);
if (!profile) {
return -1;
}
if (context->decoder_ctx && release)
{
if (context->decoder_ctx) {
LOG_TEXT("avcodec_close()");
if (avcodec_is_open(context->decoder_ctx)) avcodec_close(context->decoder_ctx);
av_free(context->decoder_ctx);
context->decoder_ctx = NULL;
}
context->decoder = NULL;
#ifdef NVIDIA_H264_DECODER
if (context->hw_decoder)
{
LOG_TEXT("nv_decoder_release()");
nv_decoder_release(&(context->nv_context));
memset(&(context->nv_context), 0, sizeof(h264_nv_decode_context_t));
context->hw_decoder = 0;
context->nv_error_count = 0;
}
#endif
}
#ifdef NVIDIA_H264_DECODER
if (hw && !context->decoder)
{
LOG_TEXT("get_nv_decoder()");
get_nv_decoder(context->av_codec_id, &(context->decoder), &(context->hw_decoder));
}
#endif
if (!context->decoder)
{
LOG_TEXT("avcodec_find_decoder()");
context->decoder = avcodec_find_decoder(context->av_codec_id);
if (!context->decoder && context->av_codec_id == AV_CODEC_ID_H263P) {
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_DEBUG, "Cannot find AV_CODEC_ID_H263P decoder, trying AV_CODEC_ID_H263 instead\n");
context->decoder = avcodec_find_decoder(AV_CODEC_ID_H263);
}
if (!context->decoder) {
return -1;
}
}
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_NOTICE, "DECODER: id=%d %s\n", context->decoder->id, context->decoder->long_name);
context->decoder_ctx = avcodec_alloc_context3(context->decoder);
context->decoder_ctx->thread_count = profile->decoder_thread_count;
if (avcodec_open2(context->decoder_ctx, context->decoder, NULL) < 0) {
return -1;
}
return 0;
}
